Eunuch

A eunuch is a man who has been castrated or emasculated, either prior to puberty or afterwards. Most people would not volunteer their young sons to become eunuchs and most men would not choose to be castrated or emasculated. Therefore, most eunuchs are slaves who have had no choice in the matter. The most famous eunuchs are the Unsullied.

In Bayasabhad, Kayakayanaya and Shamyriana 99 of 100 boys, the sons of the Great Fathers, are gelded when they reach the age of manhood and live out their lives as eunuchs, serving their cities as scribes, priests, scholars, servants, cooks, farmers, and craftsmen. Only the most promising males, the largest, strongest, and most comely, are permitted to mature, breed, and become Great Fathers in their turn.[6]

The priests of the Blind God, a deity that was once worshiped in the Valyrian Freehold, were eunuchs who wore eyeless hoods in honor of the god, for only in darkness, they believed, would their third eye open.

Eunuchs in Westeros

In Westeros castration appears to serve more as a severe punishment and deterrent. [7]Varys is a known eunuch who has risen to the influential and powerful position of Master of Whisperers. However, he was made a eunuch in Myr, not Westeros.

“Have you ever heard such singing , my love?” Hizdahr asked her. “They have the voices of gods, do they not?” “Yes,” she said, “though I wonder if they might not have preferred to have the fruits of men.”
